I had a problem with starting downloads but I'm not sure if that's the problem you're talking about. I cleared my cache, force stopped market then pulled the battery. After a reboot everything was working fine. )

Mine didn't either. I figured it had something to do with the new Sense software or maybe the LTE SIM card technology. But downloaded all my apps that I had on my DROID in under 5 mins with this BLAZING fast 4G
